Assume that matched pairs of data from a poll of Internet users who were asked if they make travel plans through the Internet result in 317 positive signs, 391negative signs, and 29 ties when the value of the second variable is subtracted from the corresponding value of the first variable. Use the sign test with a 0.10significance level to test the null hypothesis of no difference.Let ₁ denote the median of the first variable and 12 denote the median of the second variable. What are the null and alternative hypotheses?O A. Ho: 1₁ = 1₂B. Ho: 1₁ #1₂H₁:1₁ =1₂H₁:1₁ #1₂OC. Ho: 1₁ ²1₂O D. Ho: 1₁ = 1₂H₁: 1₁ <1₂H₁: 1₁ <1₂Find the test statistic.Test statistic = (Round to two decimal places as needed.)Find the P-value.P-value= (Round to four decimal places as needed.)Does the null hypothesis of no difference hold?A. Since the P-value is less than the significance level, reject the null hypothesis of no difference.B. Since the P-value is greater than the significance level, fail to reject the null hypothesis of no difference.Since the P-value is less than the significance level, fail to reject the null hypothesis of no difference.D. Since the P-value is greater than the significance level, reject the null hypothesis of no difference.O C.

A change is made that should improve student satisfaction with the parking situation at your school. Before the change, 37% of students approve of the parking that's provided. The null hypothesis Ho : p = 0.37 is tested against the alternative H.: p > 0.37 The given hypotheses are incorrect. What are the appropriate hypotheses for performing this significance test? Ho : p = 0.37; Ha :p> 0.37, where p= the true proportion of students that approve of the parking that's provided. Ho : p = 0.37; Ho : p + 0.37, where p= the true proportion of students that approve of the parking that's provided. Ho : p > 0.37; Họ : p = 0.37, where p= the true proportion of students that approve of the parking that's provided. Ho : p = 0.37; H, : p + 0.37, where p the sample proportion of students that approve of the parking that's provided. Ho : p > 0.37; Họ : p = 0.37, where p the sample proportion of students that approve of the parking that's provided.

.2.3 Assigned Media The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject Ho when the level of significance is (a) a = 0.01, (b) a = 0.05, and (c) a= 0.10. P=0.0618 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? A. Reject Ho because the P-value, 0.0618, is greater than a= 0.01. B. Reject Ho because the P-value, 0.0618, is less than a =0.01. C. Fail to reject Ho because the P-value, 0.0618, is less than oa= 0.01. O D. Fail to reject Ho because the P-value, 0.0618, is greater than a= 0.01.
